What is VPN? VPN is an abbreviation for virtual private network. It can be defined as the method that is usually applied so as to add to the privacy and the security into the public and private networks, the internet and Wi-Fi hotspots.

The reason why you get better privacy with a BPN is the fact that the initial IP address you may have been using is replaced with one that is provided by your VPN provider. This is a great way for subscribers to get an IP address from the gateway city that they may want, provided that it is offered by the VPN provider. You can use VPN to alter your location. You may be living in New York, but you can use VPN to make it look like you are in London and so on. Each VPN provider offers different gateway cities that you can select from.
